In order to obtain a direct information concerning the equilibrium vacancy concentrations and the energy of formation of a vacancy in Al, a method of combining the bulk and lattice thermal expansion measurements was used. In the present work, only the lattice thermal expansion measurements on 99.996% pure Al were made. The data obtained were analyzed using bulk thermal expansion data on Al of the same purity available in the literature. The concentration of vacancies increases exponentially with temperature and its value at the melting point is (1.1±0.2) × 10^<-3> and the energy of formation of a vacancy is estimated to be (0.64±0.12)eV.
